This study was conducted to develop functional muffin in which grape seed extract(GSE) was added at 0, 0.5, 1 or 2% levels and to evaluate the quality characteristics. The volume of muffin decreased with the increasing GSE content, but no significant differences were observed. The weight and height of muffins increased with the increasing GSE content. The incorporation of GSE in the product lowered lightness (L value) and increased redness(a value). The mechanical texture parameters including hardness, springiness, gumminess and brittleness increased with the increasing GSE levels. Sensory analysis showed that muffin prepared with 0.5% GSE was considered to be as acceptable as control, based on hedonic scale ratings given by untrained taste panel.

The purpose of this study was to evaluate the appearance, sensory and physicochemical characteristics of muffin added glutinous(GSP) and non-glutinous sorghum powder(NGSP). As increasing the amounts of sorghum powder, proximate (moisture, ash and protein) and minerals composition(K, Ca, Mg and Na) of muffin were significant difference. The weight, volume, height, lightness(L-value) and yellowness(b-value) were decreased as increasing the amounts of sorghum powder. In the results of sensory evaluation, appearance, color, flavor, taste, texture and overall quality of untreated muffin were 1.4, 1.6, 1.4, 1.0, 1.1 and 0.9, and muffin added 10% GSP and NGSP were scored relatively high. Antioxidant compounds contents of muffin added sorghum powder were increased as increasing the amounts of sorghum powder. DPPH and ABTS free radical scavenging activities on methanolic extracts of untreated muffin were 0.74 and 1.31 mg TE/g ER, respectively. DPPH and ABTS free radical scavenging activities of 100% GSP muffin were 9.40 and 19.14 mg TE/g ER, and 100% NGSP muffin were 10.59 and 18.78 mg TE/g ER, respectively. The results of this study show that notable antioxidant compounds and antioxidant activity on muffin added sorghum powder are considered to have significant health benefits.

The sensory and mechanical characteristics of muffin using different levels (0, 20, 40, 60, 80 and 100％) of Glycyrrhiza radix extract were investigated. The lightness of crust and crumb of the muffins were significantly (p〈0.05) decreased, but the redness was increased with increasing content of Glycyrrhizae radix extract. The mechanical texture parameters, such as hardness, gumminess and chewiness, were significantly (p〈0.05) low in the groups with 40∼80％ Glycyrrhizae radix extract. With regard to the sensory evaluation, a brown crust, yellow crumbs, surface roughness, Glycyrrhizae radix flavor, roasted nutty taste, sweetness, bitterness and springiness of the muffins were significantly increases with increasing content of Glycyrrhizae radix extract. However, the hardness was significantly (p〈0.05) low without the addition of Giycyrrhizae radix extract, the overall acceptability was excellent in the group with the addition of 60％ Glycyrrhizae radix extract. As a result, with the addition of Glycyrrhizae radix extract to the muffin, the sensory and mechanical properties were improved therefore, Glycyrrhizae radix extract could be prepared as a useful functional additive to sugar free muffins.

This study was performed to examine the quality and antioxidant activity of muffin containing black garlic extract powder that was stored for 9 days at room temperature. Black garlic extract powder was added to the muffin batter at concentrations of 0, 1, 4, 8, and 12%. Specific gravities of muffin batters increased as black garlic extract powder increased, whereas, height and specific volume of the muffins decreased. For the color of muffin crust and crumb, lightness decreased as the level of garlic extract powder increased, whereas redness and yellowness increased. For sensory evaluation, the color, flavor, softness, and chewiness of the muffins containing 1% black garlic extract powder were superior compared to those of other samples. Scores for taste and overall acceptability were the highest in muffin containing 4% black garlic extract powder. The antioxidant activity of muffins measured by DPPH(2,2-diphenyl-1-picrylhydrazyl) radical scavenging assay increased as the level of black garlic extract powder increased. Further, the TBARS(thiobarbutric acid reactive substance) content of the muffins containing various levels of black garlic extract powder was lower than that of control.

Cherry powder (obtained from ground fruit of Prunus serrulata L. var. spontanea Max. wils.), which is a natural functional material, was used in muffin manufacturing at different concentrations from 0, 3, 5, 7, and 10% (w/w). Muffin was evaluated for their sensory property and physical quality. The antioxidative activity measured by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity of muffin increased as the concentrations of cherry powder increased. As the concentration of cherry powder increased, the mechanical characteristics of the muffin, such as hardness increased, but gumminess and chewiness decreased. Lightness (L) and yellowness (b) of muffin decreased as the concentration of cherry powder increased, whereas the redness (a) increased. The muffins containing 3, 5, 7, and 10% cherry powder had acceptable sensory properties, such as color, flavor, taste, softness, moisture, and overall acceptability. The results exhibited that adding the cherry powder into the muffin increased antioxidant activity. The highest quality improvement was obtained by incorporating 5% (w/w) of cherry powder into the muffin formula.

The quality characteristics of muffins prepared with hesperetin (0.2, 0.4 or 0.8%), a flavonoid, were evaluated. There were no significant differences in volumes and heights of the muffins due to the various additions of hesperetin, or in the L, a and b values of the crust and crumb of the various muffin groups. The sweetness of the muffins containing the highest level of hesperetin (0.8%) gave the highest scores in the sensory test. A stepwise regression analysis showed the sweetness and after taste were the significant factors affecting the overall preference for the muffins. Therefore, hesperetin may be useful as a muffin additive as its addition did not impair the sensory characteristics of the muffins.

We examined the quality characteristics and conducted a sensory evaluation of muffins made with rice flour and the biopolymer hydroxyethyl methylcellulose (HEMC) to identify a new health functional food additive. First, overrun and foam stability of HEMC-HV (high viscosity) was better than HEMC-LV (low viscosity) to prepare muffins. Also the quality of rice muffins(volume, specific cake volume, and baking loss) was analyzed. There was no significant difference in the sensory evaluation of rice flour muffins containing foam mixture(egg white:HEMC-HV, 3:1, v/v) and muffin made from flour. The results showed that HEMC-HV was suitable for quick bread muffin-making using 100% rice flour.

The objective of this study was to determine the optimum mixing ratio of Opuntia humifusa powder and sugar in the preparation of muffin. The optimal sensory composite recipe was determined by following the central composites for muffin with different levels of Opuntia humifusa powder (A) and sugar (B). The analysis was performed using the response surface methodology, and the sensory evaluation was performed with the data. Ten experimental recipes, including two with reference points in the composition, were selected. The compositional and functional properties were measured, and the physical and sensory values were applied to the mathematical models. Perturbation plots showed the effects of each ingredient on the final product. Measurements showed significant values in lightness (p<0.05), sweetness (p<0.05), hardness (p<0.05), gumminess (p<0.05) and cohesiveness (p<0.01). The sensory measurements showed significant values in color (p<0.05), flavor (p<0.05), appearance (p<0.05), softness (p<0.05) and overall quality (p<0.05). Based on the numerical and graphical methods, the optimal formulation was determined to be 6.10 g of Opuntia humifusa powder and 82.61 g of sugar.

This study was intended to investigate the characteristics of muffins prepared with allulose which is low-calorie and physiologically functional rare sugar. Volume and specific volume of muffins increased significantly with allulose addition, but not with its contents. Muffin heights also increased as allulose was added more. Baking loss rate and moisture contents were not significantly different among samples. Allulose seemed to have nearly same water holding capacity with sucrose. Lightness of muffin crust and crumb both decreased, but redness and yellowness increased according to allulose, the reducing sugar addition by Maillard reaction. In the texture profile analysis, Hardness of AL100 was higher significantly (p<0.05) and springiness, cohesiveness and fracturability increased according to the allulose contents. In the sensory evaluation, AL0 was the sweetest and AL0 and AL25 got higher overall acceptance score. Physical characteristics were not different (p<0.05) among AL0, Al25 and AL50. As a result, 25% sucrose substitution with allulose can provide low-calorie, anti-hyperglycemic and tasty muffin.
